Abstract
This paper describes the results of a simple beam vibration test and the corresponding numerical simulation. We have been developing a structural sensing method using the wireless sensor network and the accurate small vibrator. This vibrator is able to excite very accurate harmonic vibrations to a structure with a known force function. In this study, vibration test of a simple beam was conducted and the frequency transfer function was estimated with the use of ARX model. The obtained frequency transfer function is compared with a frequency transfer function calculated by a FEM analysis. The results show that the frequency transfer function measured by the structural sensing method is successfully simulated by the FEM analysis.
